Build Your Own Poly Tunnel

As promised here are the basics on how to build your own Poly Tunnel
First concrete 4 foot lengths of scaffold tube in to the ground at 5 foot centres the quantity will depend on how the finished tunnel will be. These tubes should be 3 foot long above ground

Next fix scaffold planks to the outside of the poles on both sides and the back using builders Band 



 Next put the 50mm water or gas or gas pipe over the scaffold tubes and push down to the top of the scaffold boards to create the hoops for a 10foot wide tunnel use 19 foot lengths

Next build the frameworks at both ends using randomised cls timber from Wickes or B+Q







The hoops need bracing on the smaller tunnels I use 2x1 timber 
on the larger ones I use the same cls as the framework just screw the wood in to the pipe 
you are now ready for the sheet 
you can find the sheeting instructions here

    That looks great. Its the pipe that's the problem up here in the "artic circle" I think it is a 12ft wide one I'd want, do you have a lenght for the pipe needed per hoop?

  12. Really interested in this...how solid have you found it to be in a high wind? We're moving to north-east Scotland, and our neighbour (a farmer who grows produce for farmer's markets) lost the cover off his commercial grade tunnel twice last winter...

  16. Built one of these using yellow pipe, solid as any normal tunnel. I used 4 by 1 to run along the ridge which I bolted through using 6mm bolts. I trenched the polythene into the ground. Excellent thing and growing plenty of produce in it.
